AbstractFission barriers of actinides are calculated in the framework of the macroscopic-microscopic method. The single particle energies are obtained within a new version of the Woods-Saxon two-center shell model. A nuclear shape parametrization characterized by five degrees of freedom is used. The barriers are calculated along the minimal action trajectory in the configuration space and the inertia is evaluated within the cranking formalism. The reliability of the model is tested by comparing the theoretical results with values deduced from experimental data.

Good Agreement

Energy spectra of nuclei of masses 43 through 53 have been studied. Within the framework of the spherical shell model, we have assumed an “inert" core of 40Ca plus Z − 20 protons and N − 20 neutrons in the lf7/2 shell. With the assumption of pure configurations, two residual interactions have been investigated by treating them exactly for all states. We have first used the “realistic" effective interaction of Kuo and Brown. We have also taken the effective interaction of Dieperink and Brussaard which has been determined in a least-squares fitting procedure. Calculated low-lying states of these nuclei are in good agreement with experimental levels. Among all results, only those for 46Sc, 47V, 48Ti, and 48Cr nuclei are reported here. Some discrepancies, which arise in particular from the restriction we have made for the configuration space, remain.

Shift Point

Monopole shift in the proton states in odd neutron-rich F isotopes has been studied with neutron number changing from N = 10 to 20 for three different interactions. The variation of monopole shift point out towards appearance of shell closure at N = 14 and N = 16 and its disappearance at N = 20. Low lying states of odd F isotopes have also been calculated in the limited configuration space of sd shells for these interactions.
